BACKGROUND OF THE INVENTION 1. Field of the Invention

The invention relates generally to providing sanitized cleaning towels. More specifically, the invention relates to an automated system and method for providing sanitary towels for hospitality services, namely food and beverage establishments.

2. Description of the Related Art

In virtually every jurisdiction in the United States, restaurants and bars are required to abide by basic cleanliness and hygiene standards. Public health standards from the federal level down to the local level require not just clean, but sanitary food preparation and food service surfaces and utensils.

The United States and the rest of the world now have an increased awareness of infectious disease. Due to the COVID-19 pandemic, improved sanitizing devices and techniques are not only desired, they have become a necessary element in both living and work spaces.

Germicidal techniques including the use of various types of chemical sanitizers have been developed to combat the contamination of surfaces, and are well known in the art. Numerous methods inventions have been created and implemented to clean and sanitize surfaces for food preparation and dining.

Restaurants and bars are generally required to have a bucket of sanitizing solution for towels to be sanitized before being used to wipe down surfaces. Many institutions utilize sanitizer solution buckets at every food prep area. Towels and/or wipe cloths that are used throughout food preparation, cooking and serving processes are required to be stored in a sanitizer solution to prevent harborage of microorganisms. In restaurants and bars, a bucket filled with a sanitizer solution is the preferred method of sanitizing surfaces for food and beverage preparation as well as for sanitizing surfaces for food and beverage consumption.

A typical sanitizer solution bucket contains an aqueous solution having a recommended concentration of a chemical sanitizer, usually chlorine bleach or quaternary ammonium chloride compounds commonly known as Quat. These two types of chemical sanitizers are approved by virtually every public health agency in the United States and beyond to reduce the number of microorganisms to safe limits on eating and drinking utensils as well as surfaces.

Maintaining a sanitizer bucket in restaurants requires diligence and time. In many jurisdictions, employees must change out the sanitizing solution every two hours. In other jurisdictions, the sanitizer solution must be kept at an optimal concentration. In many instances, employees do not have the time available to maintain the sanitizer bucket. Likewise, employers do not have the financial wherewithal to operate a payroll and maintain a sanitizer bucket system.

Presently, there exists a need for an improved, low maintenance, automated system and method for providing sanitary towels for restaurants and bars. Such a system must be able to easily replace current sanitizer buckets. Additionally, such as system must be able to insure that sanitizer solution maintains a sanitizer concentration optimized to current health and safety standards. Furthermore, such a system should reduce towel cleaning and sanitizing times and costs.

SUMMARY

The present invention is directed to an improved automated system and method for providing sanitary towels for restaurants and bars. Such a system and method overcomes the limitations which currently exist in traditional sanitizer bucket systems.

At its essence, the present invention is directed to an automated system for providing sanitary towels in a sanitizer solution which includes a corrosion resistant, waterproof tank assembly, a corrosion resistant rotatable perforated drum assembly, a drive motor and drive gear assembly, said drive gear assembly movably connecting the said drive motor to the said corrosion resistant rotatable perforated drum assembly, a sanitizer solution source; a water source; a heating unit, one or more solenoid valves capable of governing the introduction and release of water from the said water source and sanitizer solution from the said sanitizer source into the said corrosion resistant, waterproof tank assembly, one or more sensors capable of measuring solution temperature, one or more sensors capable of measuring solution sanitizer concentration, and a controller unit having at least one processor and memory.

The controller unit includes at least one processor and memory to cause the system to perform the functions of powering up and starting the system, filling the corrosion resistant waterproof tank assembly with a measured amount of water by way of opening one or more solenoid valves, measuring the concentration of sanitizer in the corrosion resistant waterproof tank assembly, adjusting the concentration of sanitizer in the corrosion resistant waterproof tank assembly, measuring the temperature of the water and sanitizer solution in the corrosion resistant waterproof tank assembly, adjusting the temperature of the water and sanitizer solution in the corrosion resistant tank assembly, agitating towels in the inner cavity of the corrosion resistant rotatable perforated drum assembly, draining the water and sanitizer solution from the corrosion resistant waterproof tank assembly, and repeating the process at regular intervals so as to provide sanitary towels in a restaurant or bar setting. A user can program the controller to adjust metrics such as the concentration of sanitizer in the solution, adjust the temperature of the solution, and the time when the sanitizer solution in the corrosion resistant, waterproof tank assembly should be changed.

One object of the present invention is to provide an automated system and method for providing sanitary towels for restaurants and bars that fits in the same space as current sanitizer buckets are kept and maintained. The system is designed to fit in the same space that sanitizer buckets are currently located and may exist as a permanent fixture or as a moveable and portable implementation. All a restauranteur or innkeeper need do is clamp the system in place, plug it in, place the system's drain hose in existing drain sinks, connect a sanitizer hose attachment, adjust the system's timing cycle and start.

A further object of the present invention is to reduce the need for having towels cleaned by a professional linen provider. Because the system and method for providing sanitary towels for restaurants and bars agitates towels in a rotating drum in a solution which has the side effect of bleaching towels, the need for having towels cleaned by a third party is substantially reduced.

Another object of the present invention is to streamline the process of providing sanitary towels for restaurants and bars. Employees of restaurants and bars should be able to devote more of their time to customers and providing quality food and beverage services. Every minute not spent replacing sanitizing solution is a minute better used in other areas of the bar or restaurant.

Another object of the invention is to provide and train employees with improved sanitary techniques for restaurants and bars by providing an easy to use and low-maintenance system and method for providing sanitary towels for restaurants and bars. Through the use of the system and method for providing sanitary towels for restaurants and bars, employees will become more knowledgeable of sanitary methods and techniques and provide customers a better drinking and dining experience.

The sensor assembly 208 can further include one or more sensors capable of measuring solution sanitizer concentration. The sensor assembly 208 can further include one or more sensors capable of measuring solution pH. Additionally, the sensor assembly 208 can include one or more sensors capable of measuring solution hardness. Persons having skill in the art will appreciate that such a sensor array can be made to assume numerous configurations and conformations. Persons having skill in the art will further appreciate that numerous types of sensors from different manufacturers can be used. Of critical importance, each sensor must be able to function in a corrosive environment. Each sensor can be connected to the controller unit 106 where the controller unit can adjust metrics such as temperature and sanitizer concentration by sending signals to the system components.

In one embodiment of the invention, the system 100 is automatically filled with a water/sanitizing solution mixture. For example, and not by limitation, an inlet solenoid valve 206 may be placed on one side of the corrosion resistant, waterproof tank assembly 102. An outlet solenoid valve 206 may be placed at the bottom end of the corrosion resistant, waterproof tank assembly 102. Persons having skill in the art will readily appreciate that such valves may be opened and shut through electromagnetic solenoids or actuator motors known and appreciated in the art. Solenoid valves can regulate the amount of fluid which passes through them and are available for varying purposes. A controller unit 106 is used to govern the opening and closing of such valves, the opening and closing being timed or manually operated. Persons skilled in the art will readily appreciate that solenoid valves 206 may be used in more than one location and may be used to govern the sanitizer concentration. In one embodiment of the invention, the valves 206 are opened and closed by a solenoid mechanism which is controlled by the controller unit 106.

The water and sanitizer solution temperature inside the corrosion resistant, waterproof tank assembly 102 is governed by a heating element 210 which is configured to the controller unit 106. Persons having skill in the art will understand that there are numerous heating elements available in the art. Of primary importance is the heating element's ability to function in an environment containing corrosive or oxidative chemicals such as chlorine and chlorine-based sanitizers. A user, through the controller unit 106, can program the heating element 210 to achieve the desired temperature of the water and sanitizer solution.

FIG. 3 illustrates a diagram view of a system for providing sanitary towels for restaurants and bars in accordance with an embodiment of the invention. In this view, the system for providing sanitary towels for restaurants and bars 100 is connected to a sanitizer reservoir 302 where a sanitizer line 304 connects to a water line 306 at a mixing junction or manifold 310 where various means ranging from a simple pipe junction to a mixing chamber may be used to mix the water/sanitizer solution and regulate the concentrations thereof before it is introduced into the corrosion resistant, waterproof tank assembly 102. In one embodiment of the invention, the sanitizer line proceeds directly to the corrosion resistant, waterproof tank assembly 102 where sanitizer and water are mixed inside the corrosion resistant, waterproof tank assembly 102. Persons having skill in the art will understand that numerous ways of mixing water with a sanitizing solution are available and may be implemented into the present invention.

In one embodiment of the invention, the water source 306 is a typically plumbed water source which couples with the corrosion resistant, waterproof tank assembly 102 at a junction where local water can enter under its own pressure. A water inlet 312 located at the upper end of the corrosion resistant, waterproof tank assembly can be coupled with a solenoid valve or a float valve or any other means for governing the water level inside the corrosion resistant waterproof tank assembly. In one embodiment of the invention, a solenoid valve 206 is used to introduce water with an electronic sensor capable of determining the water level is connected to the controller unit 106. In such a configuration, the water level can be automatically governed by the controller unit 106.

In one embodiment of the invention, a dosing pump 308 is used to introduce measured amounts of sanitizer into the system. The dosing pump 308 draws a measured amount of sanitizer solution into a chamber and injects the sanitizer into the corrosion resistant, waterproof tank or water line 306 or pipe which contains the water which will ultimately become sanitizer solution. Persons skilled in the art will appreciate that such dosing pumps are powered by either an electric motor or an air actuator. Such dosing pumps and have a controller that turns the pump on and off and manages the flow rate. In embodiments of the invention, a dosing pump 308 can be configured to the controller unit 106 of the invention to introduce measured amounts of sanitizer into the corrosion resistant, waterproof tank assembly.

The sanitizing solution can be drained from the corrosion resistant, waterproof tank assembly 102 through a drain line 312 into a drain 316. In one embodiment of the invention, a solenoid valve 206 is used to drain water and sanitizer solution. Such a solenoid valve is connected to the controller unit 106. An electromechanical pump can be used to facilitate drainage. In other embodiments of the invention, the drain line 312 can be positioned in such a way that gravity and atmospheric pressure will allow for drainage.

Because many jurisdictions require that sanitizer buckets not be in direct contact with the floor or ground, the corrosion resistant, waterproof tank assembly 102 may be mounted to another surface such as a shelf or dishwasher assembly. Such a mounting means 110 may include four legs and involve simply placing the corrosion resistant, waterproof tank assembly 102 on a flat surface. In other embodiments of the invention, the mounting means 110 may include a mounting bracket or other attachment means known and appreciated in the art.

The automated system and method for providing sanitary towels for restaurants and bars may be implemented as a permanent fixture, as a retrofit kit for commercial dishwasher systems, or as a portable unit which may be set up in places where existing sanitizer buckets are used. The system and method for providing sanitary towels for restaurants and bars may be configured to obtain water and sanitizing solution from currently existing commercial dishwasher systems. In other embodiments, the system and method may configure with a conventional water spigot and a drain. In one embodiment of the invention a sanitizing solution line is coupled to the sanitizing solution used in commercial dishwashers. In some embodiments, both water and the sanitizing solution may be either pumped in or aspirated in using ordinary water pressure. Persons skilled in the art will readily appreciate that numerous means are available for performing such a function.

A controller unit 106 can be implemented to govern every component of the system for providing sanitary towels for restaurants and bars. At its most basic, a controller could simply include a series of on-off switches to power each component. However, in the preferred embodiment, a controller unit may consist of a computer implemented means which controls a plurality of basic electronic circuits which, in turn, governs each component. In embodiments of the invention, the controller unit 106 can be networked into a restaurant's security and/or surveillance system, a computer system and/or an intra- or internet system. Persons having skill in the art will further appreciate that such a system and method can be implemented with other “smart” technologies such as utilities and telecommunication networks. An interface 318 such as a LCD display, a LCD touchscreen or dial or other functional equivalent can be configured to the controller unit 106. In larger restaurants and/or bars, multiple systems may be employed and networked together. In other embodiments, the controller unit may be programmed manually or may operate on pre-installed software or firmware.

The controller unit can include a display unit The controller unit 106 may include a plurality of various selectors that enable a user to interact with the controller unit 106 and thereby enter input related to the operation of the system for providing sanitary towels. By way of example, and not limitation, the controller unit 106 may include a power selector 320 to turn the system 100 on or off, a button temperature selector 322 for choosing a desired temperature to be used when a user interacts with the controller unit 106, a programming selector 324 for setting user-defined operation cycles, and a sanitizer concentration selector for setting recommended sanitizer concentration levels. Other examples of selectors 326 include a start/stop selector to initiate, pause, and/or resume an operation cycle and a stop selector or to terminate or pause an operation cycle.

In the preferred embodiment of the invention, a 110 volt power source is used. However, other power sources may be configured to operate the system depending on location and power availability. The components are 24 volt components known and appreciated in the art. The electric components can be governed through a controller unit 106. Persons having skill in the art will appreciate that numerous means and methods can be employed to implement such a system.

FIG. 4 illustrates a typical computer system that, when appropriately configured or designed, may serve as a computer system for which the controller unit 106 of the system for providing sanitary towels for restaurants and bars, and the components thereof, may be embodied. The computer system 400 includes at least one processor 402 (also referred to as central processing units, or CPUs) that may be coupled to storage devices including a primary storage 406 (typically a random-access memory, or RAM), a primary storage 404 (typically a read-only memory, or ROM). CPU 402 may be of various types including micro-controllers (e.g., with embedded RAM/ROM) and microprocessors such as programmable devices (e.g., RISC or SISC based, or CPLDs and FPGAs) and devices not capable of being programmed such as gate array ASICs (Application Specific Integrated Circuits) or general purpose microprocessors. As is well known in the art, primary storage 404 acts to transfer data and instructions uni-directionally or bi-directionally to the CPU and primary storage 406 typically may be used to transfer data and instructions in a bi-directional manner. The primary storage devices discussed previously may include any suitable computer-readable media known and appreciated in the art. A mass storage device 408 may also be coupled bi-directionally to CPU 402 and provides additional data storage capacity and may include any of the computer-readable media described above.

It will be understood by persons having skill in the art that memory storing computer readable instructions that, when executed by the at least one processor, cause the system for providing sanitary towels for restaurants and bars, by at least one processor, to perform the steps of powering up and starting the system, filling the corrosion resistant waterproof tank assembly with a measured amount of water by way of opening one or more solenoid valves, measuring the concentration of sanitizer in the corrosion resistant waterproof tank assembly, adjusting the concentration of sanitizer in the corrosion resistant waterproof tank assembly, measuring the temperature of the water and sanitizer solution in the corrosion resistant waterproof tank assembly, adjusting the temperature of the water and sanitizer solution in the corrosion resistant tank assembly, agitating towels in the inner cavity of the corrosion resistant rotatable perforated drum assembly, draining the water and sanitizer solution from the corrosion resistant waterproof tank assembly, and repeating the process at regular intervals so as to provide sanitary towels in a restaurant or bar setting. A user can program the controller to adjust metrics such as the concentration of sanitizer in the solution, adjust the temperature of the solution, and the time when the sanitizer solution in the corrosion resistant, waterproof tank assembly should be changed.

The invention can be further implemented as machine readable instructions detailing a method for operating a system for providing sanitary towels for restaurants and bars wherein the controller unit 106 controls functions such as, but not limited to, powering up and starting the system; filling the corrosion resistant waterproof tank assembly with a measured amount of water by way of opening one or more solenoid valves; introducing a measured amount of sanitizer solution into the corrosion resistant waterproof tank assembly by opening one or more solenoid valves; measuring concentration sanitizer in the corrosion resistant waterproof tank assembly with measured amount of water and sanitizer solution; adjusting the concentration of sanitizer in the corrosion resistant waterproof tank assembly with measured amount of water and sanitizer solution to required levels; measuring temperature of water and sanitizer solution in the corrosion resistant waterproof tank assembly; adjusting the temperature of water and sanitizer solution in the corrosion resistant waterproof tank assembly; draining the water and sanitizer solution from the corrosion resistant waterproof tank assembly. Further memory instructions such as a general method and workflow model shall be described in further detail.

FIG. 5 is a flow diagram of a method for providing sanitary towels for restaurants and bars in accordance with an embodiment of the invention. The steps of such a flow diagram may be readily implemented through the use of a networked or non-networked controller unit 106 using a microprocessor or microcontroller means. A user can program metrics of the system's timing cycle through the controller unit. Such metrics include, but are not limited to, sanitizer concentration, solution temperature, motor speed, and fill and drain interval times.

The system is first powered up and the method of providing sanitary towels for restaurants and bars starts 502. For example, and not by way of limitation, the unit may be powered up upon a trigger by a motion sensor or video camera by a manager or employee entering the building. In embodiments of the invention, the system can be manually started by pressing a button or switch on the controller unit 106.

The system will then autofill the corrosion resistant, waterproof tank assembly with a measured amount of water 504. When activated, the controller unit will open one or more solenoid valves, or other suitable equivalent of a solenoid valve, which will allow water to enter the corrosion resistant, waterproof tank assembly. The water level can be governed by numerous means known and appreciated in the art. By way of example, a float valve could be used to keep a solution at a constant level. In other embodiments of the invention, the water can be measured by way of a sensor or flow meter. In one embodiment of the invention, the preferred amount of water and sanitizer mixture can measure anywhere between two and ten gallons depending on user requirements.

When the required amount of water is introduced into the corrosion resistant, waterproof tank assembly, a quantity of sanitizer mixture 506 is added or introduced to create a water and sanitizer solution. In one embodiment of the invention, the mixing of water and sanitizer solution is performed in a manifold outside of the corrosion resistant waterproof tank assembly. In other embodiments, the mixing of water and sanitizer solution is performed inside the corrosion resistant waterproof tank assembly. One or more sensors capable of measuring solution sanitizer concentration measures the concentration 508 of sanitizer in the water and sanitizer solution. The controller unit, through use of a dosing pump, can introduce measured amounts of sanitizer into the water and sanitizer solution until the concentration of sanitizer is at a desired level.

The system will then adjust the temperature of the water and sanitizer solution inside the corrosion resistant, waterproof tank assembly 102. A user can set the temperature 510 by programming the control unit. A sensor in the sensor array will measure the temperature. If the temperature is less than the desired temperature, the controller unit with activate the heating unit to raise the temperature. When the sensor detects the correct temperature 512, the controller unit will then turn off the heating unit.

Once the proper sanitizer concentration levels and proper temperatures have been achieved, a user may then add towels 514 to the corrosion resistant rotatable perforated drum assembly 104 of the corrosion resistant, waterproof tank assembly 102 506. Users can add towels at any time in the cycle. However, a minimum time in the system is recommended in order to insure the towels are sanitized before use. After the corrosion resistant, waterproof tank assembly 102 is filled with sanitizer solution and towels are inserted, the system begins to spin or move the corrosion resistant rotatable perforated drum assembly 516 thereby agitating and thoroughly sanitizing the towels. This agitation or spin cycle may be performed at timed intervals depending on need. The controller unit can allow for numerous user programs. After a given amount of time, the solution must be changed—in one instance two hours 518. The controller unit drains the corrosion resistant, waterproof tank assembly 520 by opening a solenoid valve and allowing the solution to drain. Draining can be achieved by a pump or by simple gravity and atmospheric pressure. The corrosion resistant rotatable perforated drum assembly can be programmed to spin or to remain stationary while the corrosion resistant waterproof tank assembly is drained. If the restaurant or bar is still open and use of the system is still required, the system can be refilled and reused 522. If not, then the drained system can be shut down 324. Persons having skill in the art will readily appreciate that these steps may be implemented through numerous means and methods. Persons having skill in the art will readily appreciate that other steps may be incorporated into such a method to facilitate or improve the method.
